1. Field of the Invention
The present invention relates to a control valve for a water tap.
2. Description of the Prior Art
A conventional control knob is disposed on the upper end of the water pipe for controlling water supply. As washing hands, the user has to hold water with hands and then spray water in his hands to the control knob, thus cleaning the control knob; however, such a cleaning method will waste water.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a control valve for a water tap that can control water supply easily from an outlet extension of the water tap.
A further objective of the present invention is to provide a control valve for a water tap that can save water effectively.
Another objective of the present invention is to provide a control valve for a water tap that can be produced at lower cost and in less time.
A control valve for a water tap comprises a connecting member, a drain member, and a stop assembly, wherein the drain member is screwed with the connecting member, and between the drain member and the connecting member is defined a passage, the drain member includes a plurality of outlets formed on the bottom thereof for communicating with the passage and for flowing water outwardly, the stop assembly is defined between the connecting member and the drain member, such that as the drain member is rotated to the first position, the water flows out of the outlets through the passage, and as the drain member is rotated to the second position, the stop assembly closes the passage to stop water flow.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to
As shown in
Furthermore, the large-diameter portion 113 of the connecting member 11 is also screwed with the outlet connection 51 with external thread (not shown) of the water tap 5 by using its internal thread, thus connecting the control valve 1 and the water tap 5 together. It is to be noted that the external and internal threads may be alternatively provided on the outer and inner rims of the large-diameter portion 113 of the connecting member 11. When the large-diameter portion 113 is eliminated from the control valve 1, the small-diameter portion 112 of the connecting member 11 still can be screwed with the outlet connection 51 of the water tap 5 by its external thread, thus connecting the control valve 1 and the water tap 5 together as well.
The drain member 12 of the control valve 1 includes an open end and a closed hollow end. The drain member 12 includes an annular cylinder 121 and a bottom 122 both affixed therein, wherein the inner diameter of the annular cylinder 121 is equal to the outer diameter of the small-diameter portion 112 of the connecting member 11 so that the small-diameter portion 112 can be inserted into the cylinder 121. In addition, a plurality of longitudinal recesses 1211 are arranged around the outer surface of the cylinder 121 so as to enhance the friction of the drain member 12 with the finger, hence the drain member 12 is easy to be rotated by the user. Moreover, a knob extension 1213 is radially attached to the cylinder 121 so that the user rotates the drain member 12 easily. Likewise, on the outer rims of the connecting member 11 and the drain member 12 are provided a plurality of first and second planes 114, 124 respectively so that the user rotates the connecting member 11 and the drain member 12 by way of a wrench (not shown), such that the connecting member 11 is engageably screwed with the outlet connection 51 of the water tap 5 and the drain member 12.
Referring further to
The upright shaft 131 further includes a peripheral rib 1311 provided on the top of the large-diameter portion thereof, and the stop washer 132 is fitted to the interface of the large-diameter and small-diameter portions of the upright shaft 131. As desiring to wash hands, the drain member 12 is rotated downward to the first position as illustrated in
With reference to
In the second embodiment of the present invention, the description related to the same components as the first embodiment of the present invention would be omitted. The different components of the control valve 1 for the water tap according to the second embodiment of the present invention from the first embodiment of the present invention includes an upright shaft 231 disposed on a bottom 222 of a drain member 22, and a connecting member 21 having a retaining portion 214 mounted in a through hole (as shown in
It is to be noted that the retaining portion 214 may also be formed in other shapes. For example, as shown in
With reference to in
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
